You need a robot to pick up after hammerbot, and that’s shovelbot. The shovel is a bit small and the camera is a bit large, and also I’d like the camera mount to tilt down enough to see what gets scooped into the shovel. Then shouldn’t the shovel have some kind of tilt mechanism so that it can dump its load into wagons?

Well, the reason you make these graphics is to see the problems before you go to the expense of actually building the thing.
